Don't know, sometimes you have to rely on whatever is said by the technician, especially when one doesn't have anything concrete to doubt, and also when one has worked with him in the past. A few good electricians call him 'ustaad' in every sense of the word, I guess :). He already warned that soldering might render the whole motherboard dysfunctional, so can't blame him either.
Got 2 used ones, 1 was a mile-o-meter showing speed till 120 (must be taken off from a London model), and the other looked alright, installed that and got the problem mentioned above.
Currently the car is at the silencer workshop, put in the old adjuster for the moment to get the car on-road and get some much needed work done, will go to the denter for a minor dry dent repair on rear fender in the evening. Till that time the adjuster will arrive in sha Allah, fingers crossed, and will be installed. If that goes alright, tomorrow will be the inter cleaning day, followed by the visit to the seat covers shop who will dismantle all the seats except the driving seat. The Nazimabad guy has given some hope about the repair of air vents, he didn't say no altogether so there's a glimmer of hope that a few bucks might be saved here.
1 tyre is not looking good, and there's a shortage of funds to replace all 4 at the moment. Search is on for a similar treads used one to give us a breather of 2-3 months till we're able to replace all 4. That's a crucial decision to make as the next 3-4 months are the toughest on tyres because of the heat wave and Karachi's road conditions.
I hope I'm not boring you guys by constantly whining about one problem or the other. The idea is to get experts' opinion as well as letting others like myself understand how painstakingly tedious, sometimes to the extent of frustratingly slow this process of building a vehicle for your own use is. Not to forget the monetary aspect of it, we had started with a time frame of 15-20 days within a budget of 75-80k in mind and here we are on the 23rd day and 110k later, fearing another 100k more (tyres included) needed to get the vehicle in a shape to our liking.
